On Sunday, April 7 2002 at 2am, Daylight Savings Time begins.
Please ensure your windfarm is in the following configuration. Plant PCs should have "Automatically adjust clock for daylight saving changes" NOT checked - Double-click on time in lower right corner of Plant PC to verify/configure - During site commissioning, all WTGs should have been configured for NOT checked. Park PC should have "Automatically adjust clock for daylight saving changes" NOT checked - Double-click on time in lower right corner of PC to verify/configure - During site commissioning, Park PCs should have been configured for NOT checked. Required Action Park PC must be manually adjusted for the time change. Time synch program must be running from Park PC. - Reference SUB 374, distributed in February 2002. - Note: Time synch program must be manually restarted any time the Park PC re-boots. Discussion The Time synch program will synchronize all WTG PCs The Time synch program runs on the Park PC The Park PC must NOT be set to automatically adjust for Daylight Savings time because this will cause the Time synch program to send the incorrect time to the WTGs (This is because Microsoft Windows uses Greenwhich Mean time and converts to local time, including Daylight Savings) Time-synch must not be checked at Plant or Park because a Windows prompt appears at 2am April 7 asking if automatic update to Daylight Savings Time is OK. This prompt requires a person to manually respond. If the PC re-boots before the manual response, the PC will not complete its boot process because it is again waiting for a manual response to the prompt. This means that VisuPro will not start, and will not collect WTG data from the Bachmann. Verification of Plant PCs "Automatically adjust clock for daylight saving changes" NOT checked can be performed from the Park PC after 2am April 7. Look at the WTG time on the Network Overview screen. Any WTGs that are one hour different require configuration at the WTG. If questions, contact Ron Brzezinski, Joe Chapman, or Alaadin Suliman. Thank you. Ron
